Among other things, Garwin was the author of the actual design
used in the first hydrogen bomb
(code-named Mike) in
1952.[5] He was
assigned the job by Edward Teller, with the instructions that
he was to make it as conservative a design as possible in order to
prove the concept was feasible (as such, the Mike device was not
intended to be a usable weapon design, with tons of cryogenic
equipment required for its use).[6]
